Description of the Related Art Heretofore, as this kind of orifice disk, there has been known an orifice disk in which an annular orifice is formed in an outer peripheral portion by stacking a pair of plates, and a housing chamber for housing a movable plate is formed in a central portion. A molded product made of a synthetic resin is used as the pair of plates, and the outer peripheral portions of the two are caulked and fixed by a member on the liquid seal mount device side and polymerized (for example, JP-A-57-9340). See) or
There has been proposed an apparatus in which one is press-fitted into the other and press-fitted to each other using a metal-made bottomed cylindrical plate by press molding (for example, see Japanese Utility Model Publication No. 2-39067). By the way, the accommodation chamber is 0.1 to 0.1 mm with respect to a predetermined internal interval in the main vibration input direction set in advance in relation to a movable plate that moves inside in the main vibration input direction at the time of high frequency vibration input.
It is necessary to form it with an accuracy of 0.2 mm or less. If this interval changes beyond a predetermined range, the desired high-frequency attenuation performance cannot be exhibited.

Creep strain may be generated by the pressure for caulking and fixing the outer peripheral portion, and warpage or a gap may be generated between the joining surfaces, and the interval between the main chambers in the main vibration input direction may change. Further, when a press-formed product is used, the plate wall portion forming the storage chamber is distorted during the press-fitting process, or the plate thickness of the plate wall portion is slightly changed, so that the storage is performed in the same manner as the synthetic resin molded product. The interval of the main vibration input direction of the room may change.

じてしまう。On the other hand, in order to solve these problems, a pair of disks opposed to each other across a through hole of the pair of plates is formed separately from a pair of plates forming an orifice. It is conceivable that the two joints of a pair of disks are superposed to form a storage space at a predetermined interval between the opposing surfaces of the disks. In this case, it is necessary to fix the pair of disks to the two plate-shaped members by sandwiching the pair of disks from both sides in the plate thickness direction of the edge of the hole constituting the through hole. However, since there is a minute variation in the plate thickness due to a manufacturing error of the plate-like body, it is conceivable that it affects the interval of the main chamber in the main vibration input direction. That is, when the plate thickness is larger than the reference value, the space between the storage chambers directly fluctuates, and in addition, by forcibly overlapping the two joints, bending distortion occurs in each disk, and the space fluctuates. Conversely, if the thickness is smaller than the reference value, rattling occurs.

Since the joints of the pair of disks are superposed and integrated by ultrasonic welding, the gap between the internal storage chambers is formed to be a predetermined value. In addition, the projections of each disk sandwich a pair of plate-like bodies superimposed on each other from both sides in the main vibration input direction, and the respective projections are melted by the ultrasonic welding and adhered to the joining surface of the plate-like bodies. Since the plate is fixed in a state, even if there is a variation in the thickness of the plate-like body, the variation is absorbed by the melting of the protrusion, and the variation in the thickness does not affect the interval between the storage chambers. Therefore, no distortion or warpage occurs in each disk, and no creep distortion or distortion due to the press-fitting operation when the accommodation chamber is formed by swaging or the like.

Even if the pressure of the sealed liquid acts on the pair of disks, the communication holes and the reinforcing ribs are arranged so as to overlap in that direction, so that the communication holes of each disk overlap in the main vibration input direction. In comparison with the above, the distortion is suppressed, and the damping performance due to the movement of the movable plate in the accommodation chamber is maintained at a constant level.

Compared to the case of high-frequency welding means for applying heat and pressure by applying a vibration having an amplitude of 1.0 to 3.0 mm at 0 to 240 Hz, the interval between the accommodation chambers 18 formed inside is made to be a predetermined one. be able to.

の状態で平衡状態になる。Next, the operation and effect of the liquid ring mounting device will be described. For example, an automobile engine is mounted on the mounting plate 2 via mounting bolts 2b, and the leg 7b of the mounting bracket 7 is mounted on the leg 7b of the mounting bracket 7, for example. The structural member is mounted. As a result, the weight of the engine acts on the support member 1 and deforms downward to push the liquid 11 in the working chamber 9, so that the liquid 11 is pushed into the opening 12 of the orifice board 5.
d, flows through the orifice 17 and the opening 13f to the equilibrium chamber 10 side, and the diaphragm 6 is swelled downward, and the equilibrium state is established in this state.

Accordingly, the liquid 11 inside flows between the working chamber 9 and the equilibrium chamber 10 through the orifice 17, and the vibration such as the low frequency is attenuated and absorbed by the flow resistance of the liquid 11 at this time.

行うことができる。On the other hand, when high-frequency vibrations that do not substantially cause the flow of the liquid 11 through the orifice 17 into the liquid-ring mounting device and cause so-called rigidification of the liquid 11 are input in the vertical direction, the high-frequency vibrations are input. Fluid pressure fluctuation acts on the movable plate 16 in the orifice board 5 through the communication holes 14d and 15d, and the movable plate 16 moves up and down in the storage chamber 18 to change the volume on the working chamber 9 side. Therefore, the high-frequency vibration can be effectively attenuated and absorbed.

ことができる。At this time, since the upper and lower spaces of the storage chamber 18 are formed with high precision at a predetermined height, a predetermined attenuation and absorption performance against the high frequency vibration can be surely exhibited. Further, the communication holes 14d, 15d in the upper and lower substrate portions 14a, 15a constituting the accommodation chamber 18 do not overlap with each other in the vertical direction, and the other communication holes 14d or 15d do not overlap with each other in the vertical direction. Reinforcement ribs 15e
Or 14e, the upper and lower communication holes 1
As compared with the case where 4d and 15d are overlapped in the vertical direction, it is possible to suppress the occurrence of bending of the substrate portions 14a and 15a due to the pressure of the liquid 11. Therefore, at the time of inputting the high frequency vibration, the volume fluctuation in the accommodation chamber 18 between the movable plate 16 and the substrate portion 14a or 15a can be kept almost constant, and the variation of the frequency peak can be suppressed. Since it can be made substantially constant, efficient attenuation can be performed.

In addition, the protrusions of the respective disks sandwich the pair of plate-like bodies superimposed on each other from both sides in the main vibration input direction, and the respective protrusions are melted by the ultrasonic welding and adhered to the joining surfaces of the plate-like bodies. Since it is fixed in a state, even if there is a variation in the plate thickness of the plate-like body, the variation can be absorbed by melting of the projections, and the occurrence of distortion of each of the disks due to the variation in the plate thickness Can be reliably prevented. Thereby, the interval between the storage chambers can be more reliably and more precisely, and a predetermined damping performance can be reliably exhibited for high-frequency vibration.
